This invention has reference to the art of sizing warp yarn and the object of the invention is to provide an improved immersion roller assembly for use with the sizing box to the end that whereas formerly two sizing operations were substantially resorted to, through the medium of the present invention but a single sizing box and a single sizing operation may be required while at the same time more efiicient sizing of the yarn is obtainable.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a view partly in section and partly in elevation illustrating the application of the invention.

Figure 2 is a fragmentary plan view with certain parts shown in section.

Figure 3 is a fragmentary vertical sectional view showing the mechanism for raising and lowering the roller assembly.

Figure 4 is a sectional view through the roller assembly.

Figure 5 is an elevational view of the roller assembly, and

Figure 6 is a fragmentary sectional view showing the manner of connecting the side members of the frame forming part of the roller assembly.

Referring to the drawings by reference numerals it will be seen that 5 indicates the yarn to be sized, 6 the beams from which the yarn is fed to the sizing box I, while 8 indicates the roller usually, provided at the inlet end of the box I and over which the yarn 5 is trained, while 9 indicates generally the first pair of squeeze rolls, and ill the second pair of squeeze rollers. The above is conventional and is not of the essence of the present invention.

In accordance with the present invention there is provided an improved immersion roll assembly indicated generally by the reference numeral II. The assembly I I comprises a frame structure consisting of a pair of identical substantially inverted U-shaped side members l2 the legs of which are connected by tie rods l3 respectively secured at their respective ends to the legs of the members 12 by pairs of inner and outer nuts I4 as clearly shown in Figures 5 and 6. Supported between the lower ends of the legs I26. of the side members I2 is an immersion roller l5 while a second immersion roller I6 is journalled and supported between the lower ends of the legs l2b of the frame members l2.

The legs l2a, l2b of the side members l2 are adapted to extend into the solution 11 within the tank or box I and the legs I2a operate between pairs of suitable guides l8 secured to opposite side walls of the box 1 inwardly from the 5 end wall of the box on which the roller 8 is sup-; ported as clearly shown inFigure 1.

Secured to and in line with the legs I211. are rack bars l9 and these bars may be secured to the ends of the legs l2a in any suitable manner as by being integral therewith or as otherwise found desirable.

The rack bars I 9 are in constant mesh with pinion wheels 20 provided adjacent the ends of a transverse shaft 2| that has the ends thereof 15. suitably journalled in the side walls of the box or tank 1. On one end thereof the shaft 2| is equipped with a handle 22 and also with a ratchet wheel 23 with which is engageable a dog 24 pivotally mounted on a'suitable bracket 25 arranged on the adjacent side wall of the box I.

In actual practice and as is clearly shown in Figure 1 the device I l is mounted so as to position the rollers l5 and I6 transversely of the box I with the legs 12a operating between the guides l8l8 and the rack bars IS in mesh with the pinions 20. It will be further noted that the side members l2 of the frame H are spaced from but straddles the first pair of squeeze rollers 8 so that, as shown inIigure 1 the yarn 5 first passes under the first immersion roll l5, then between the first set of squeeze rolls 9, passing from between these rolls 9 under the second immersion roller l5, and from the roller l5 between the rollers H) to pass from the box I. In this connection it will be noted that in passing under the rollers l5 and IS the fabric 5 passes through the solution I1, and by operating the hand wheel 22 the rollers l5, l5 may be placed atany desired depth. Also the device l'l may be readily raised to facilitate the initial training of the yarn 5 under the rollers l5 and l5.

From the above it will be apparent that through the medium of the roller assembly of this invention an immersion of the yarn 5 into the solution 1 is made prior to and also subsequent to the passage of the yarn 5 through the first set of squeeze rollers- 9. Thus two immersion or dipping operations of the yarn 5 is accomplished without resort to the passing of the yarn through a sizing solution in a second sizing box as heretofore was necessary due to the fact that at the present time the practice has generally been to pass the yarn 5 directly from the rollers 9 to the rollers In with I a result that after passing between the rollers 9 there is no further immersion of the yarn until the yarn is fed to a second sizing box, whereas in accordance with the present invention a second immersion operation takes place, and this second operation takes place during the passage of the yarn from the first set of rollers 9 to the second set of rollers ID as before explained.

Having thus described my invention, what I claim as new is:

1. In combination with a sizing box having side walls, an immersion roller assembly comprising a pair of inverted U-shaped members and tie rods connecting said members, guide means mounted on the said side walls of the sizing box, and said side members having one leg thereof engaging said guide members whereby said side members are supported for vertical movement, immersion rollers supported between said side members at the lower ends 01 the legs or said side members, and means forvertically adjusting said side members.

2. In combination with a. sizing box having side walls, an immersion roller assembly comprising a pair of inverted U-shaped members and tie rods connecting said members, guide means mounted on the said side walls of the sizing box, and said side members having one leg thereof engaging said guide members whereby said side members are supported for vertical movement, immersion rollers supported between said side members at the lower ends of the legs of said side members, and means for vertically adjusting said side members, said means including a shaft extending transversely of the sizing box, pinions on said shaft, and depending rack bars connected with one leg of said side members and meshing with said pinions, and handle means for the shaft for rotating it.
